Introgression and species delimitation in the longear sunfish Lepomis megalotis (Teleostei: Percomorpha: Centrarchidae)

Daemin Kim, Bruce Bauer & Thomas Near
Introgression and hybridization are major impediments to genomic-based species delimitation because many implementations of the multispecies coalescent framework assume no gene flow among species. The sunfish genus Lepomis, one of the world’s most popular groups of freshwater sport fish, has a complicated taxonomic history. The results of ddRAD phylogenomic analyses do not provide support for the current taxonomy that recognizes two species, L. megalotis and L. peltastes, in the L. megalotis complex. Instead, evidence from...
